Pigment Information

This color contains the following pigments:

PO48-Quinacridone Gold

PB27-Prussian Blue

PY3-Hansa Yellow 10G


Pigment Name

PO48-Quinacridone Gold

Pigment Type

organic, quinacridone

Chemical Formula

C20H12N2O2 or C20H10N2O4

Properties

Quinacridone Gold is a high performance pigment. It lacks brightness and cleanliness in tints, and it may disperse unevenly. It has an average drying time. Quinacridone pigments have relatively low tinting strength in general. For this reason, quinacridone colors are often expensive, because more pigment is required in the formulation.

Permanence

Quinacridone Gold has excellent lightfastness and is considered the most lightfast pigment in its shade range.

Toxicity

Quinacridone gold is not considered toxic. Overexposure to quinacridone pigments may cause skin irritation. Quinicridone pigments contain a compound found to be a skin, eye, and respiratory irritant.

History

Although quinacridone compounds became known in the late 19th century, methods of manufacturing so as to make them practical for use as commercial pigments did not begin until the 1950s. Quinacridone pigments were first developed as coatings for the automotive industry, but were quickly adopted by artists.


Pigment Name

PB27-Prussian Blue

Pigment Type

inorganic

Chemical Name

ferric ferrocyanide/iron(III)-hexacyanoferrate(II)

Chemical Formula

Fe7(CN)18(H2O)x or C6FeN6H4N

Properties

Prussian Blue is a semi-transparent, deep cyan-blue with a greenish undertone and a very high tinting strength unequaled by most pigments. It is similar to Phthalo Blue unless mixed with white, when it gives up intensity and becomes smoky. It can behave erratically and less reliably in oil and watercolor form depending on its manufacture. For permanent painting Phthalo Blue is considered a more reliable choice.

Permanence

Prussian Blue is lightfast and permanent in all techniques except for fresco. When mixed with Zinc White in watercolor or tempera form, it fades upon exposure to light and completely regains its chromatic strength in the dark. Modern manufacturing techniques have made this tendency less of an issue in recent years

Toxicity

Prussian Blue is moderately toxic if ingested. It will emit toxic hydrogen cyanide gas if heated, exposed to ultraviolet radiation, or treated with acid.

History

 The first of the modern pigments Prussian Blue is the first artificial pigment with a known history. It was discovered by accident in 1704 by the Berlin color maker Heinrich Diesbach, who was trying to create a pigment with a red hue by mixing iron sulfate and potash. The potash Diesbach purchased from a local laboratory had been contaminated by animal oil and blood during previous experimentation. The resulting mixture yielded a very pale red that changed to purple and then deep blue when he tried to concentrate it. Since previous blue pigments came from lapis lazuli, an expensive stone, Diesbach's discovery was extremely important for artists of the time.


Pigment Name

PY3-Hansa Yellow 10G

Pigment Type

organic, monoazo

Chemical Formula

C16H12CL2N4O2

Properties

This Hansa yellow is a transparent yellow. It has great brightness and tinting strength and its drying time ranges from average to slow. Hansa Yellow makes more intense tints and cleaner secondaries than Cadmium Yellows, especially when mixed with other organic or modern colors like Phthalo Blue and Green. Because they are more transparent, they have great value as glazing colors.

Permanence

This Hansa Yellow has fair to good permanence, particularly in the lighter shades.

Toxicity

Hansa Yellow has no significant acute hazards, though its chronic hazards have not been well studied.

History

Hansa Yellows were first made in Germany just before WW1 from a series of synthetic dyestuffs called Pigment Yellow. They were intended to be a synthetic replacement for Cadmium Yellow.
